Saib cov duab loj dua
Valve yog ib qho ntawm cov khoom siv tseem ceeb hauv kev tswj cov kua dej.Tam sim no, cov ntawv thov tseem ceeb ntawm lub valve suav nrog roj av thiab roj, hluav taws xob, tshuaj lom neeg engineering, dej thiab dej phwj kho, ntawv ua thiab metallurgy.Ntawm qhov ntawd, roj & roj, hluav taws xob thiab tshuaj lom neeg kev lag luam yog qhov tseem ceeb tshaj plaws ntawm kev siv valve.Raws li kev twv ua ntej los ntawm McIlvaine, kev ua lag luam kwv yees, qhov kev thov ntawm kev lag luam valve yuav ncav cuag 100 billion las.Energy xav tau nyob rau hauv cov teb chaws tsim yog lub ntsiab tseem ceeb los txhawb kev lag luam valve kev lag luam los tsim.Nws tau kwv yees tias txij xyoo 2015 txog 2017, qhov kev loj hlob ntawm kev lag luam valve loj yuav tswj tau li ntawm 7%, ntau dua li kev loj hlob ntawm kev lag luam thoob ntiaj teb valve.
Valve yog tswj kev tivthaiv rau cov dej sib kis, muaj cov haujlwm ntawm kev txiav tawm, kev hloov kho, kev hloov pauv dej, tiv thaiv kev tiv thaiv tam sim no, kev tiv thaiv hluav taws xob, shunt lossis overflow thiab decompression.Valve yog cais rau hauv kev lag luam tswj valve thiab pej xeem valve.Kev lag luam valve yog siv los tswj kev khiav tawm ntawm kev tshaj tawm, siab, kub, chaw nres tsheb dej thiab lwm yam kev ntsuas.Raws li cov qauv sib txawv, kev lag luam valve tuaj yeem muab faib ua ntau hom.Rau hom kev cai, valve tau muab faib ua kev cai, txiav tawm, kev tswj hwm thiab txiav tawm;nyob rau hauv cov nqe lus ntawm cov ntaub ntawv ntawm valve, valve yog muab faib ua hlau, uas tsis yog-hlau thiab hlau liner;Raws li kev tsav tsheb, kev lag luam valve tau muab faib ua hom hluav taws xob, hom pneumatic, hom hydraulic thiab phau ntawv hom;Raws li qhov kub thiab txias, valve tau muab faib ua ultralow kub valve, tsis tshua muaj kub valve, qhov kub thiab txias valve, nruab nrab kub valve thiab siab kub valve thiab lub valve tuaj yeem muab faib ua lub tshuab nqus tsev valve, tsis tshua muaj siab valve, nruab nrab siab valve, siab siab valve thiab ultra. siab siab valve.
Suav valve kev lag luam yog los ntawm 1960's.Ua ntej xyoo 1980, Tuam Tshoj tsuas tuaj yeem tsim ntau tshaj 600 pawg thiab 2,700 qhov ntev ntawm cov khoom siv valve, tsis muaj peev xwm tsim lub valve muaj qhov tsis zoo thiab cov ntsiab lus siab.Txhawm rau ua kom tau raws li qhov xav tau ntawm lub valve muaj qhov tsis zoo thiab cov ntsiab lus siab tshaj plaws tshwm sim los ntawm kev lag luam thiab kev ua liaj ua teb hauv Suav teb tau tsim, txij li xyoo 1980's.Tuam Tshoj pib siv txoj kev xav sib txuas kev ywj pheej ntawm kev txhim kho thiab kev qhia txog kev siv tshuab los tsim cov tshuab valve.Qee lub tuam txhab tseem ceeb valve txhim kho kev tshawb fawb thiab kev tsim kho tshuab, tsa lub siab ntawm kev xa khoom siv tshuab valve.Tam sim no, Tuam Tshoj twb tau tsim lub rooj vag valve, lub ntiaj teb valve, throttle valve, pob valve, npauj npaim valve, diaphragm vale, ntsaws valve, kos valve, kev ruaj ntseg valve, txo valve, ntws valve thiab lwm yam valve, suav nrog 12 pawg, ntau tshaj 3,000. qauv thiab 40,000 qhov ntev.
Raws li qhov zoo li qub ntawm Valve Ntiaj Teb, lub ntiaj teb kev lag luam xav tau rau kev lag luam valve muaj qhov drilling, kev thauj mus los thiab kev ua phem.Roj & roj muaj feem ntau tshaj plaws, ncav cuag 37.40%.Kev thov rau lub hwj chim thiab tshuaj engineering raws li, raws li accounting rau 21.30% thiab 11.50% ntawm lub ntiaj teb no industrial valve xav tau.Kev lag luam xav tau hauv thawj peb daim ntawv thov suav nrog 70.20% ntawm tag nrho cov lag luam xav tau.Nyob rau hauv Suav teb, chemical engineering, fais fab thiab roj & roj kuj yog lub khw muag khoom tseem ceeb ntawm valve.Qhov kev thov rau valve feem suav nrog 25.70%, 20.10% thiab 14.70% ntawm tag nrho cov kev thov.Tus nqi xav tau suav rau 60.50% ntawm tag nrho qhov xav tau valve.
Nyob rau hauv cov nqe lus ntawm kev lag luam xav tau, qhov kev thov rau valve hauv kev txuag dej thiab hydropower, nuclear fais fab nroj tsuag thiab roj av kev lag luam yuav muaj kev sib raug zoo yav tom ntej.
Hauv kev txuag dej thiab hluav taws xob, cov tswv yim tshaj tawm los ntawm General Office ntawm Lub Xeev Pawg Neeg Saib Xyuas tau taw qhia tias los ntawm 2020, lub peev xwm ntawm cov pa hluav taws xob yuav tsum ncav cuag li 350 lab kilowatts.Kev loj hlob ntawm hydropower yuav ua rau muaj kev xav tau loj rau lub valve.Kev loj hlob tsis tu ncua ntawm peev ntawm hydropower yuav txhawb kev vam meej hauv kev lag luam valve.
